Welcome to the AMD FSR™ SDK 2.2.0 - "Redstone"
The AMD FSR™ SDK is a collection of heavily optimized technologies that can be used by developers to improve their DirectX® 12 or Vulkan® applications.
The FSR™ SDK includes:
| FSR™ SDK Technique | Samples | GPUOpen page | Description |
|---|---|---|---|
| FidelityFX™ Super Resolution (Temporal) 2.3.4 | FidelityFX™ FSR sample | FidelityFX™ Super Resolution 2 | Offers a temporal (multi-frame accumulation) solution for producing high resolution frames from lower resolution inputs. |
| FidelityFX™ Super Resolution (Upscaler) 3.1.5 | FidelityFX™ FSR sample | FidelityFX™ Super Resolution 3 | Offers a temporal (multi-frame accumulation) solution for producing high resolution frames from lower resolution inputs. |
| FSR™ Upscaling (ML-Upscaler) 4.1.0 | FidelityFX™ FSR sample | FSR™ Upscaling 4 | Offers a machine learning-based solution for producing high resolution frames from lower resolution inputs. |
| FidelityFX™ Super Resolution Frame Generation 3.1.6 | FidelityFX™ FSR sample | FidelityFX™ Super Resolution Frame Generation 3 | Offers generation of interpolated frames from multiple real input frames, and multiple sources of motion vector data. |
| FidelityFX™ Super Resolution Frame Generation SwapChain 3.1.6 | FidelityFX™ FSR sample | FidelityFX™ Super Resolution Frame Generation Swapchain 3 | A replacement DXGI Swapchain implementation for DX12 which allows for additional frames to be presented along with real game frames, with relevant frame pacing. |
| FSR™ Frame Generation (ML) 4.0.0 | FidelityFX™ FSR sample | FSR™ Frame Generation 4 | Offers generation of interpolated frames from multiple real input frames, and multiple sources of motion vector data. |
| FSR™ Frame Generation SwapChain (ML) 4.0.0 | FidelityFX™ FSR sample | FSR™ Frame Generation Swapchain 4 | A replacement DXGI Swapchain implementation for DX12 which allows for additional frames to be presented along with real game frames, with relevant frame pacing. |
| FSR™ Ray Regeneration (ML-Denoiser) 1.1.0 | FidelityFX Denoiser sample | FSR™ Ray Regeneration | Offers a machine learning-based solution for denoising. |
| FSR™ Radiance Caching (Preview) | FidelityFX NRC (Preview) sample | FSR™ Radiance Caching (Preview) | Offers a machine learning-based solution for path tracing result caching. |
Further information
Known issues
| AMD FSR™ SDK Sample | API / Configuration | Problem Description |
|---|---|---|
| All FSR™ SDK Samples | All APIs / All Configs | Windows path length restrictions may cause compile issues. It is recommended to place the SDK close to the root of a drive or use subst or a mklink to shorten the path. |
| All FSR™ SDK Samples | Vulkan / All Configs | Vulkan is currently not supported in SDK 2.2 |
